Concept
Genuine progress indicator
Summary
Genuine progress indicator (GPI) is a metric that has been suggested to replace, or supplement, gross domestic product (GDP). The GPI is designed to take fuller account of the well-being of a nation, only a part of which pertains to the size of the nation's economy, by incorporating environmental and social factors which are not measured by GDP. For instance, some models of GPI decrease in value when the poverty rate increases. The GPI separates the concept of societal progress from economic growth.
The GPI is used in ecological economics, "green" economics, sustainability and more inclusive types of economics. It factors in environmental and carbon footprints that businesses produce or eliminate, including in the forms of resource depletion, pollution and long-term environmental damage. GDP is increased twice when pollution is created, since it increases once upon creation (as a side-effect of some valuable process) and again when the pollution is cleaned up; in contrast, GPI counts the initial pollution as a loss rather than a gain, generally equal to the amount it will cost to clean up later plus the cost of any negative impact the pollution will have in the meantime. While quantifying costs and benefits of these environmental and social externalities is a difficult task, "Earthster-type databases could bring more precision and currency to GPI's metrics." It has been noted that such data may also be embraced by those who attempt to "internalize externalities" by making companies pay the costs of the pollution they create (rather than having the government or society at large bear those costs) "by taxing their goods proportionally to their negative ecological and social impacts".
GPI is an attempt to measure whether the environmental impact and social costs of economic production and consumption in a country are negative or positive factors in overall health and well-being. By accounting for the costs borne by the society as a whole to repair or control pollution and poverty, GPI balances GDP spending against external costs.
